Date of creation:
13.03.2006.Scale:
1:20 000 000.Accuracy of the map:
It is created on materials of maps of natural scale 1:17 000 000 - 1:100 000 000.Projection:
"Alber's Equal Area Conic for the USSR", 9, 1001, 7, 100, 0, 44, 68, 0, 0.Basic content:
Vector map. Area of distribution is shown by polygon (main distribution) and by dots (sporadic distribution). Zone of weediness is shown by polygon.Accuracy of the classifier:
Within the weed area of G. pachycarpa, the zones of its weediness are shown, established by criteria of occurence (% of fields where this species is found) and abundance (expressed as projective cover of this species in the field (in % to the field area)) (Tanskii et al., 1998), i.e.; where the occurence of this species exceeded 20% with its abundance (projective cover) more than 15%.Method of map production:
The zones of distribution and weediness of G. pachycarpa are established according to the analysis of the published maps and literature. The area of distribution is based on the map from the publication of Chikov P.S. (1983); the map of Volkov A.N. (1935) served as reference source while adjusting the eastern and northern limits of the area. The zones of weediness are established according to Nikitin V.V. (1983) and specified by the border of arable land. The sites of sporadic distribution of G. pachycarpa are depicted according to ILDIS database (Roskov, 2005), part of them, supported by the data of Volkov A.N. (1935) and Chikov P.S. (1983), is included in the main area.Reference citations:
